How to improve responsiveness of TreeView scrollbars

[tictac1234]

Hello, I am a Game Engine developer.

I am considering creating an editor using WinUI due to its beautiful design. However, I’ve noticed that when dragging the scrollbar in a TreeView, the responsiveness to the mouse feels approximately two frames slower compared to Unity.
(The video demonstrates this comparison, with WinUI on the left and Unity on the right.)

I recorded a comparison with WPF as well.

Is there currently a way to improve this responsiveness?

If eliminating this lag is not possible at the moment, is there a chance it may be addressed in a future update?

I was considering migrating my game tool from WPF to WinUI, but WPF clearly has better responsiveness.
If this cannot be improved, I am inclined to continue using WPF for now…

Thank you very much for your time and assistance.
